Диметиламиноэтил-метакрилат

Description

Dimethylaminoethyl methacrylate (DMAEMA) is a functional ester of methacrylic acid with a tertiary amino group in the side chain. Belongs to the class of aminomethacrylate monomers. The tertiary nitrogen atom is easily protonated by acids and quaternized by alkylating agents, so the monomer serves as the basis for cationic polymers and copolymers.

Basic Attributes

Appearance and physical properties

• Appearance: transparent liquid from colorless to light yellow
• Density lower than water
• Does not dissolve in water
• Vapors are heavier than air and tend to travel along the ground

Heating and storage behavior

The vapors of the substance are irritating and corrosive to the eyes and mucous membranes of the respiratory tract. The monomer is capable of spontaneous exothermic polymerization when heated or when contaminated with foreign substances (acids, radical polymerization initiators, metals). If polymerization begins inside a closed container, the vapor pressure and heat of reaction can rupture the container. When burned, the substance decomposes to form toxic nitrogen oxides. Toxic if in contact with skin, if swallowed or if vapors are inhaled, therefore work requires ventilation and protective equipment.

Scope of application

DMAEMA is a monomer for cationic polymers: flocculants, coagulants, dispersants and stabilizers used in water treatment and paper production. Homopolymers and copolymers of DMAEMA with methyl methacrylate, ethoxytriethylene glycol methacrylate, or N-vinylpyrrolidone are being studied as DNA carriers and transfection agents in biomedical development, including drug delivery systems and tissue engineering. Copolymers with antibacterial properties are used to control the adhesion of biofilms on surfaces.

• production of plastics and textile materials
• Modifier in coatings, adhesives and textile finishing - increases adhesion, hardness and water resistance
• antistatic agents and lubricating oil additives
• leather processing products (tanning, finishing)
• cationic precipitants and emulsifiers
• combustion accelerators

Storage and transportation

Store in a hermetically sealed container, away from heat sources, open flames, acids and polymerization initiators; control the residual content of polymerization inhibitor in the batch. Transport and store separately from oxidizing agents. The room must be dry and well ventilated. When working with monomer, protective gloves, goggles or a mask are required, as well as respiratory protection - contact with skin and eyes, as well as inhalation of vapors cause irritation and corrosive damage to tissues.
